lib.systems: drop scaleway-c1
These servers apparently no longer exist, since September 2, 2021[1].
If somebody needs this for non-Scaleway machines, they should suggest
its reintroduction with a different name.

Merge pull request #161156 from a-m-joseph/abort-on-failed-platform-detection-instead-of-silently-assuming-pc
platforms.nix: use {} on failed detection instead of silently assuming pc

006c38fa53 platforms.nix: use {} on failed detection instead of silently assuming pc
This patch causes the autodetection code in lib/systems/platforms.nix
to return {} if it cannot detect the platform and one of the
platform.nix-detection-provided attributes (linux-kernel, gcc, and
rustc) are accessed, rather than silently assuming the "pc" platform
as was previously done.

It is definitely safe to assume that code using these attributes is
prepared to deal with `gcc` and `rustc` not being defined, because
many of the working entries in this file don't define it.

Regarding `linux-kernel` the situation is less certain, but some code
(`lib/systems/default.nix` for example) is already designed to deal
with that attribute being missing.  At worst it would result in an
"attribute not found" error.

While adding mips64el bootstrap support to nixpkgs, the silent
assumption that mips64el routers are actually Intel PCs caused
significant frustration.  This commit removes that assumption in order
to save people who port nixpkgs to new platforms in the future from
this frustration.

3e60871330 lib/systems/platforms.nix: use "32" instead of "o32" for mips32 ABI
There is only one ABI for 32-bit MIPS chips.  Before mips64, it didn't
really have a name.

The 64-bit MIPS ABI comes in two flavors, "n64" and "n32".  It is
commonplace to refer to the old 32-bit ABI as "o32" (MIPS and SGI
documents do this).

However, when configuring gcc, one must use --with-abi=32, not
--with-abi=o32.

Let's keep GCC happy with this commit.

12371a51e6 lib/systems: add mips64el definitions
MIPS has a large space of {architecture,abi,endianness}; this commit
adds all of them to lib/systems/platforms.nix so we can be done with
it.

Currently lib/systems/inspect.nix has a single "isMips" predicate,
which is a bit ambiguous now that we will have both mips32 and mips64
support, with the latter having two ABIs.  Let's add four new
predicates (isMips32, isMips64, isMips64n32, and isMips64n64) and
treat the now-ambiguous isMips as deprecated in favor of the
more-specific predicates.  These predicates are used mainly for
enabling/disabling target-specific workarounds, and it is extremely
rare that a platform-specific workaround is needed, and both mips32
and mips64 need exactly the same workaround.

The separate predicates (isMips64n32 and isMips64n64) for ABI
distinctions are, unfortunately, useful.  Boost's user-scheduled
threading (used by nix) does does not currently supports mips64n32,
which is a very desirable ABI on routers since they rarely have
more than 2**32 bytes of DRAM.

525c69e724 lib/systems: fix scaleway-c1 platform
This regressed in 9c213398b3

The recursiveUpdate gave the platform both gcc.cpu and gcc.arch attrs
instead of only gcc.cpu. This is invalid; gcc configuration fails with:

```
Switch "--with-arch" may not be used with switch "--with-cpu"
```

So we revert to using `//` to retain only gcc.cpu
(which is more specific than the processor arch).

805e9ce9ea platforms: Build flat kernel image for RISC-V
Newer bootloaders for RISC-V (i.e., OpenSBI + U-Boot) support
flat and compressed kernel images but not vmlinux. Therefore,
let's build "Image" like what we do with aarch64.

Also copy DTBs while we are at it.

7b573e8051 lib/systems/platforms: remove TI_CPTS override
Forcing the module to be builtin breaks 5.10, which wants to compile it as a
module (probably due to dependencies). There doesn't seem to be a need to have
it builtin anymore, so we can just remove the override.

408ae0b13a lib: fix typo in platforms.nix
In 9c213398b3 kernelPreferBuiltin was
moved/renamed to linux-kernel.preferBuiltin. However, for
armv7l-hf-multiplatform the new option was written with an uppercase P,
which made the kernel build process ignore it.

8929989614 lib: Clean up how linux and gcc config is specified
The `platform` field is pointless nesting: it's just stuff that happens
to be defined together, and that should be an implementation detail.

This instead makes `linux-kernel` and `gcc` top level fields in platform
configs. They join `rustc` there [all are optional], which was put there
and not in `platform` in anticipation of a change like this.

`linux-kernel.arch` in particular also becomes `linuxArch`, to match the
other `*Arch`es.

The next step after is this to combine the *specific* machines from
`lib.systems.platforms` with `lib.systems.examples`, keeping just the
"multiplatform" ones for defaulting.

lib/systems/platforms: treat missing cpu version as generic pcBase
Since 40e7be1 all ARM platforms that didn't have a parsed cpu version
(e.g. arm-none-eabi) would be handled as armv7l-hf-multiplatform which
did break building arm-trusted-platform packages for some targets (e.g.
rk3399).

Using pcBase as fallback, instead of armv7l-hf-multiplatform,
corresponds with the behaviour we had before 40e7be1.

837fe2e491 platforms.nix: Remove now unused kernelMajor
The last use of `kernelMajor` in Nixpkgs was removed in 2018.

Even then, I'm not positive it was actually in an exercised code path.

AFAIUI this is now totally redundant and useless as it really was meant
for the 2.4 -> 2.6 transition.

1c10efc912 add generic x86_32 support (#52634)
* add generic x86_32 support

- Add support for i386-i586.
- Add `isx86_32` predicate that can replace most uses of `isi686`.
- `isi686` is reinterpreted to mean "exactly i686 arch, and not say i585 or i386".
- This branch was used to build working i586 kernel running on i586 hardware.

* revert `isi[345]86`, remove dead code

- Remove changes to dead code in `doubles.nix` and `for-meta.nix`.
- Remove `isi[345]86` predicates since other cpu families don't have specific model predicates.

* remove i386-linux since linux not supported on that cpu

9c50ae6898 lib, treewide: Add missing MIPS arches, and fix existing usage
Existing "mips64el" should be "mipsel".

This is just the barest minimum so that nixpkgs can recognize them as
systems - although required for building individual derivations onto
MIPS boards, it is not sufficient if you want to actually build nixos on
those targets
